Circuit Configuration
Quick-response Input Operation and Timing
With quick-response input function these High-density I/O
Modules can read short-pulse input signals, such as those from
photomicrosensors.
With standard I/O Modules, an input must be ON during the I/O
refresh period for it to be read into the PLC. Input signals
shorter than the cycle time can be missed, unless they happen
to occur during the I/O refresh.
The quick-response input buffer (on our High-density and
Mixed I/O Module) is used to hold input signals as short as
1 ms or 4 ms (selectable) allowing them to be read into the IR
area during the next I/O refresh. (Any pulse that is equal to or
longer than the minimum time setting affects the program during
the next program execution.)
The quick-response input function is available on input points
number 08 to 15 on CN2.
DC Input: ID215
I/O Refresh Instruction
The I/O Refresh instruction, IORF(97), can be used with
the quick-response input function to read the input status
held in the quick-response input buffer whenever needed
in a program.

When 00000 is ON, all words from St
to E will be refreshed.
St and E would be 101 for Unit #0,
making bits IR 10108 to IR 10115
quick-response input bits.

Machine Number Setting and Input Bit No.
When set to machine No.: n (0 to 9), words [100+10n+1]
can be used as input bits. Input bits 08 to 15 of word 1n1
can be used as quick-response
inputs.
Example: When set to 8,
input bits 18108 to 18115
become quick-response
inputs.
